JCTVC-M0382 Crosscheck of JCTVC-M0366 proposed by Qualcomm [J. Kim (LG)] [late] JCTVC-M0323 Palette Mode for Screen Content Coding [L. Guo, M. Karczewicz, J. Sole (Qualcomm)]
(Discussion chaired by D. Flynn.)
This contribution introduces a palette-based coding method. The palette mode is a CU mode designed for the coding of screen content where each CU only consists of very limited distinct values. For lossless coding, an average bit rate reduction of 25.9% for RGB 4:4:4 screen content and 13.2% overall is observed for AI coding. The method is also tested for non-lossless coding configurations.
